The currently defined behaviour seems intuitive to me, from a starting point of Perl 5. The difference between: my $new = [EMAIL PROTECTED]; and: my $new = [EMAIL PROTECTED]; is that the second one is a copy; square brackets always create a new anonymous array rather than merely refering to an existing one, and that's the same thing that's happening here. Think of square brackets as meaning something like Array->new and each one is obviously distinct. > And I feel this way because [1,2] looks like it should be platonically > unique.
